In this paper, in order to increase the scalability of the communication network, a three-level method of hierarchical coordination routing in multi-area network is proposed, which is based on the principle of goal coordination. The method is based on the decomposition representation of the flow-based routing model and it includes three levels of the calculation hierarchy: at the zero level, the routing...
The method of segment hierarchical coordination routing in multi-area network has been proposed. The method based on decomposed implementation of How-based model of inter-area routing and goal coordination principle. In this method on the lower level, there is the calculation of the routing variables, and on the upper level, there is the coordination of the solutions obtained from lower level for...
In this paper for the first time the mathematical model and the two-level method of fault-tolerant inter-domain routing in telecommunications networks was presented. The novelty of the model is its decomposed representation and formulation the inter-area interworking conditions. The implementation of these conditions guaranteed the connectivity of calculated inter-area paths. The research of the proposed...
The improvement of the scalability of routing decisions is quite relevant in modern telecommunication networks. In this regard, effective approach is associated with the implementation of hierarchical routing. This involves carrying out a structural and functional decomposition of the network, based on the introduction and supporting of multi-level routing decisions. However, the existing protocol...
To improve scalability of multicast routing solutions the method of hierarchical routing with coordination was proposed. It is based on the decomposition representation of the flow-based model of multicast routing. The usage of this method allowed decentralizing the calculation of the multicast routes in the border routers of telecommunication networks.
In this paper the flow-based model of multicast routing was researched. To improve the scalability of the network the hierarchical approach of the network is used because usage of centralized schemes is very resource-intensive. Due to disagreement of solutions obtained on routers and thus appearance of the link overloading and the subsequent package lost we proposed to use the goal coordination method...
To avoid overload of links, as well as packet loss in the network uses the coordination method. This method is based on the possibility of converting the original minimization problem in a simpler maximization problem and the solution of this problem using a two-level iterative computational structure. In this paper the analysis of convergence of the two-level hierarchical routing method with coordination...
